Patented June 24, 1930 UNITED STATES PATENT JOSEPH E. WOOD, OF DETROIT, MICHIGAN, ASSIGNOR, BY MESNE ASsIGNMENTS, TO

FOUT ADVERTISING CORPORATION, DELAWARE OF DETROIT, IsIIOHIGAN, A CORPORATION OF ADVERTISING DEVICE Application filed April 10,

. This invention relates to advertising devices in which the advertisements are printed upon a plurality of leaves somewhat like the leaves of a book and means is provided whereby the leaves may be turned one by one at regular intervals.

The object of the present invention is to simplify the Construction of a device of this character and provide an advertising mechanism of this character in which holders are provided for the leaves, permitting the leaves to be changed and thus change the advertising matter.

A further object is to provide improved means of a very simple character whereby the leaves may be rotated one by one to thus display different pages ofadvertisements.

Another object is to so construct the advertising device that the display cards or leaves will fit closely together at the center, permitting the two cards to be joined by a thin strip of adhesive tape or other equivalent means to thus form what may be termed one wide display card, these joint display cards entirely concealing any mechanism behind and supporting the display cards.

vA. further object is to provide a construction of this character wherein the display card holders are loosely mounted upon a slightly tilted shaft and an arm is provided constantly rotated by a motor around the axis common to the holders, the arm carrying a latch or equivalent member which, at one point in the rotation of the arm, is projected to engage a holder, the latch then acting to carry the holder around with the arm through approximately one hundred and eighty degrees and then releasing the holder so that the leaf or card will remain in this display position until it is again engaged by the arm.

Other objects will appear in the course of the following description.

My invention is illustrated in the accompanying drawings, wherein Figure 1 is a side elevation partly in section of my advertising device;

Figure 2 is a top plan view thereof;

Figure 3 is a fragmentary front elevation, the parts broken away;

Figure 9 is a perspective view of the cam.

Referring to these drawings, 10 designates a base which is angularin cross section so that the portion 11 of the base may rest flat down upon any suitable surface. This base carries upon it the upright portions 12 and 13 in which the bearings for certain shafts are mounted as will hereinafter appear. The middle of the base is formed with two upwardly extending lugs or ears 14L forming a bearing for a transverse shaft and one end of the base is flanged at 15 so as to form a seat 16 at one end and at the other, the flange is formed with an inwardly extending portion 17 for a purpose which will be later stated.

Mounted upon the base in any suitable way as by means of a bracket engaged with the boss 17 is an electric motor 18, the shaft of which is outwardly extended as at 19 and carries upon it the worm 20, this shaft being supported in the bearings 14 i. Mounted upon the portion 12 is a worm wheel 21 engaged by the worm 20 and carried by the hub of this worm wheel is a pinion 22 in turn engaging with a gear wheel 23.

Mounted on the stud 2 1 carried by member 17 is a shaft 24: carrying an arm 25. This shaft 2& is rotated by any suitable means from the gear wheel 23 and I have illustrated for this purpose a shaft 26 operatively driven from the wheel 23 and carrying upon it a worm 27 engaging the gear wheel 28 mounted upon the shaft 2 1. It will be understood that any suitable means may be used, however.

Extending into a socket 29 formed in the shaft 24 is a headed pin 30 and mounted to rotate around this headed pin are a plurality of angular members 31, each of which is formed at its outer end with a U-shaped portion 32. The inner end of each member 31 is flattened. andapertured for the passage of the pin 30. Mounted upon these members 31 are the placard or card frames 33 which are approximately U-shaped in form and approximately U-shaped in cross section.

-These frames, because of their U-shaped cross section permit cards to he slid into the frames. There are as many of these frames as there are cards to be displayed, and the upper arm of each frame 32 is in turn engaged with amember 31 such as previously described.

It will be seen from Figure 3 that the angular portions of the members 31 are of different heights so that while the eye portions of the members 31 are disposed one above the other upon the pin 30, the lower and upper bars of the frames 32 will be dis posed in alinement with each other. The

. upper members 31 are held joined for common rotation by a pin or shaft 34:.

For the purpose of'rotating these frames 32 one by one at intervals, to thereby display one by one the reading matter on the faces of the cards, I provide-the-arm 25-before re ferred to, This arm carries pivoted to its end thelatch or detent 35 which is held pivoted upon the extremity of the arm by means of the screw 36. This detent 35' in plan view is angular as will be seen from Figure 4:. Thelatch at What may be termed its rear end is formed with the upwardly projecting lug 36 adapted, when the latchis raised, to engagebehind; any one-of: the frames 32. At its pivotal end, the latch is provided with a foot 37, the face of which is disposed parallel to the face of the latch 35. A spring 38 urges the rear end of the latch downward against thestop 39 and, therefore, urges the foot portion 37 into angular relation to the plane of rotation of the latch.

Mounted upon the front wall of the base is an arcuate cam 40 having lugs 41 whereby it may be attached to the front wall, this cam extending through an arc of approximately 180. One end of the cam is attached to the outer face of the front wall of the base, while the other end of the cam extends inward beyond this front wall. This cam is so disposedwith relation to the arm 25 and the latch35 that as the arm moves in a clock wisedirection in Figure 2 the heel- 37 of the latch ordetent, which as before remarkedis inclined to the plane of rotation of the latch or detent, will strike against the-end of the cam 40 which will tilt the heel to bring its lower facein contact with. and parallel to the: upper faceUofF the cam. This will raise the rear end of the latch ordetent to the positionshowninFigure 5so that the latch will engage behind the first frame of the series.

In the rotation of the arm 25, this cletent i the latch will release its engagement with the first frame of the series. In moving the first frame of the series into position as the last frame of the series, the moving frame will bear against the next adjacent frame which in turn is bearing against its next adjacent frameand so on and the final movement of the frame which is engaged by the latch will cause amovement of all of the frames into such position that the frame on the other end of the series will be brought into position directly opposite the frame which is engaged with the latch. As soon. as the latch is released from the frame which has been moved, the latch drops down beneath all of the other frames of the series and the arm 25 carries the latch beneath all the other frames of the series through an angle of approximately 180 until the latch is again raised and engaged with the frame at the end of the series. Thus it will be seen that at every rotation of the arm 25, one of the frames will be moved from a position at the right hand of the machine to a position at the left hand of the machine and the next succeeding frame brought into the position of the first frame.

Thus the separate pages as they may be termed or frames will be shifted in the same manner as the leaves of a book are turned except, in the embodiment illustrated, in a reverse direction.

Obviously if the latch is turned in the opposite direction from that shown and the position of the cam is changed and the arm 25 moves inv a counterclockwise direction, the several frames supporting the leaves or cards will be shifted from left to right'in the same direction as the leaves of a book are ordinarily shifted in-reading.

It is intended that the cards shall bear reading matter on both faces. and this machine is particularly designed to support and turncards on which the reading matter may run right across both cards. The inner edges Ii:

of the display cards fit closely together adjacent the center of rotation so that these inner margins may be joinedby a thin strip of adhesive tape of like material designated 42 to thus form a single display card extending entirely across the machine. In this machine, there is no central shaft or column but the top set of hinges 31 are engaged by a pin or screw 34 as previously described which extends up into the top wall of a cabinet in which the machine is housed, it being understood, of course, that the cabinet is open at its front.

This device is particularly intended for use as a window display and it will be noted that the base is so constructed that the book as it may be termed formed of the various leaves or display cards will be disposed at an angle to the horizontal so that it may be read by persons looking down through the window. Of course, however, I do not wish to be limited to this as under some circumstances, this display device might be mount- I ed on the level with the eyes of the observer and in that case the leaves of the so-called book will be disposed in a vertical plane.

It will be seen that with this construction the display leaves are turned around in a complete circle instead of being turned through 180 one after another and then the leaves reversed, thus doing away with the complicated mechanism necessary for reversing the movement of the leaves and doing away also with the necessity which is present in some mechanisms of turning all of the leaves first from the right to the left and then one by one from left to right which tends to prevent the reading matter under these last named circumstances from being properly displayed. While I have illustrated an advertising device in which the leaves are turned in a clockwise direction, it will be obvious that the structure may be so formed as to turn the leaves in a counterclockwise direction without any change in the principles of operation.

It will also be obvious that many minor changes might be made in the details of con-- struction and arrangement of parts without departing from the spirit of the invention as defined in the appended claims.

I claim 1. All advertising mechanism including in its organization a plurality of rectangular leaf-holding frames having eyes in their upper and lower ends, means pivotally engaging the upper and lower eyes and motor operated means acting to intermittently turn each one of said leaf holding frames through an angle of approximately 180, the inner margin of the leaf of any one frame being connected to the inner margins of the leaves of an adjacent frame whereby to permit advertising matter to extend across two leaves.

2. An advertising machine including in its organization a plurality of rectangular leaf holding frames mounted for independent rotary movement on a common axis, a constantly rotated motor driven arm mounted on the same axis, a latch pivoted upon the end of the arm and having an upwardly extending nose at one end and adjacent its pivot a downwardly extending foot having a flat lower face, means urging the nose of the latch downward, and a cam extending through an angle of approximately 180 disposed in the path of movement of said latch, the upper edge of the cam being hori zontal and engaging the under face of the foot to cause the latch to tilt upward and bring its nose behind the forwardmost frame on one side of the pivotal axis, the contacting flat faces of the foot and said cam acting to hold the latch in this position while the latch and frame are moving through an angle of approximately 180, the cam then releasing the latch to permit it to drop downward and move through the remainder of its path of travel with the latch depressed.

3. An advertising mechanism including in its organization a base, a motor carried thereby, a stud projecting upward from the base and having a socket in its upper end, a shaft mounted upon said stud for axial rotation and constantly driven from said motor, said shaft carrying an arm, a pin engaged in the socket in said stud, a plurality of leaf-holding frames having upper and lower eyes, the last named pin passing through the lower eyes, a supporting pin passing through the upper eyes, the eyes being freely rotatable upon said pins, the arm being disposed below said frames, and means causing the arm to automatically engage with the forwardmost frame on one side of the axis and remain in engagement therewith while the frame is moving through an angle of approximately 180, said means then releasing the arm from its operative engagement with the said frame and after a predetermined time causing the arm to engage the serially next frame on the opposite side of the axis of rotation.

4. An advertising mechanism including upper and lower members, each provided with an eye, each member at its outer end being formed with a channeled portion, the channel being radial to the eye, and an advertising leaf having a marginal frame channeled in cross section to embrace the leaf, the inner ends of the channel-shaped frame being adapted to be inserted in the channelshaped portions of said eyes.

In testimony whereof I affix my signature.
